Hi, I'm only presenting my idea with these how I think we should be able to deal with graphs in the API, so these are completely untested, and obviously I can't say for certain if the idea works or not. I will try to test these using custom ACPI tables, but of course these should be tested on DT platform as well, so if somebody can do that, I would much appreciate.
